Thank you Shawn for your response. Yes it is true that I am a little on the tired side. I shall try to get to bed earlier.

Is opening up the sacrum supposed to help with the pain in the uppper back? Or will it help with my posture so that I can sit in a way that will help my back?

I am sitting on a chair most of the time. I have been trying to sit with my legs crossed but I have been unable to do it for more then fifteen minutes so far. Oddly enough even though am unable to sit with my back completely straight with my legs crossed. I feel no pain in my upper back. It seems to be only when I am sitting straight in a chair.

Thanks again for your attention to this matter.
